87 camaro -littlr or no fuel pressure after replacing pump

[m0t0r]

i need to know if an improperly installed fuel pump would show little or no fuel pressure, and i need a picture that shows the pump and sending unit

Did you replace the filter and check the regulator? Try restricting the return line from the regulator to see if pressure will go higher. Here is a pic of a complete unit.

/thanks for the picture,it helped alot , i think the problem is at the pump were the pump connects to the sending unit, instead of a hose , there is some type of black quick connecter where the pump plugs into the fuel line ,i think it must be bleeding off there, because it did not have a tight fit. what do you think about replacing that black connecter with a hose and clamps

[cuda_dude]

did your pump come with an instal kit? I could be thinking about the wrong thing but thats what the kit comes with, a hose to make that connection.

[m0t0r]

thanks for that info, the kit came with everything but that piece, which explains why i am losing fuel pressure, do you agree?

Another thing that happens is if there is plastic inside the fuel strainer, you will hear it snap if you push it onto the pump with the palm of your hand. The plastic breaks and leaves little splinters that are then sucked into the pump and cause the pump to lock up.

I think the black peice you're referring to is a resonator which is used to quiet pump nose.

Your problem lies elsewhere, probably the regulator, which is normally replaced with the pump hand in hand anyway. Do as HotZ28 has already suggested, pinch the return line and see if pressure increases.

Just to double check a goofey thought, is this a TBI or TPI? There is a substantial pressure difference in specs between the 2.

[m0t0r]

it is a multi port

i already replaced the regulator and fuel filter , and i installed the hose where that black resonator was, and still getting no fuel pressure , this is killing me i already removed the tank three times in the last three days

[wrightz28]

The pump is receiving power?

Waht lead you to replce the pump in the first place?

[m0t0r]

wasn,t getting fuel and could not hear the pump, what do you think about the pick-up coil being bad,

its multi port, what goofey thought do you have im desperate?

[m0t0r]

the car was running fine , then it just quit , would not start,

[wrightz28]

The goofey thought was if you had a TBI which runs less than 1/2 the pressure of a TPI.

Anyway, there is a fuse on the right hand fender above the battery in a black weather pack, has a black and orange wire running to it, check that bad boy, it's a quiet problem maker.

[m0t0r]

no i checked that fuse , its good
